Towards improved visual stimulus discrimination in an SSVEP BCI

Towards improved visual stimulus discrimination in an SSVEP BCI

The dissertation investigated the influence of stimulus characteristics, electroencephalographic (EEG) electrode location and three signal processing methods on the spectral signal to noise ratio (SNR) of Steady State Visual Evoked Potentials (SSVEPs) with a view for use in Brain-Computer Interfaces...
